SAGL - Crop Protection

Proficiency Testing Schemes

SAGL offers different Proficiency Testing Schemes on National level as well as international level.  Kindly find the attached for more information on the Proficiency Testing Schemes offered by the SAGL. 

PROFICIENCY TESTING SCHEMES PARTICIPANT APPLICATION FORM

The number of participants per Proficiency Testing Schemes varies, as an example: For the Wheat and Flour Proficiency Testing Scheme approximately 25 Labs participate regularly.

The SAGL Proficiency Testing Schemes Process is as Follows:

  • Specific action dates are scheduled for different Proficiency Testing Schemes and the frequencies are indicated in the attached Proficiency Testing Scheme Summary.
  • Participant receives a quotation at the beginning of the applicable month from SAGL for the specific Proficiency Testing Scheme.
  • The participant forwards the order number to the SAGL for invoicing purposes.
  • SAGL couriers the samples to the participants according to the SAGL’s Proficiency Testing Scheme year planner.
  • Participant receives a result sheet included in the sample consignment for reporting of results.
  • Participant has approximately 1 month to report results; the reporting date is indicated on the result sheet.
  • Participant forwards results reported on the result sheet provided, to SAGL by email. The SAGL compiles a Test Report with the results of all the participants, the participants are however only identified by SAGL assigned numbers to ensure confidentiality.  SAGL forwards the report by email to all participants. Each participant receives only their own Laboratory number in a separate email from the SAGL.

If your company is interested to participate in one or more of these Proficiency Testing Schemes, please complete the participant application form and email it to me if completed from the downloaded PDF. Please note, it is recommended but not necessary to participate in all 4 or 6 tests/year.

You are welcome to contact me if you require more information or spesific details.
